F601-Z Doubler

Post by Spike »

Its been a while, but hey, I'm back here in the chronicles section ....

I read the plans 20 times, made notes to make sure that I didn't mess up the F601-Z doubler and I did it anyway. *sigh* :( So basically what I did was to only apply the "flush head on aft side" note to the nut plates to which the fuel pump will attach. That is to say the 4 rivets that hold the nut plates on have their flush heads aft side, the rest have their flush heads forward side.

According to the fuel pump drawings found later in the plans it looks as if I might be O.K. because the pump does not touch the doubler where the other rivets are. Can anyone who has that pump mounted confirm or deny this? I'd appreciate any insight you can give.

Okay, I went to look at mine today, but I couldn't see it well enough to get a good look. So, I went back to find some pictures to get a better idea...

Here's my doubler-

I didn't use the holes for the nut plates provided for some reason, but they are still close to the plans location.

And here's the pump installed-

Obviously we can't see the bottom side of the pump, but it has the same mounting flange as the side we can see. You will be fine...worse case, you would have to trim some of the flange to clear that bottom right rivet, but I doubt it will interfere.

I looked at the plans 20 times too.. and then a few builders logs. In the end it seemed that the orienetation really didn't matter. So, I purposely decided to put the flush side forward to keep the firewall as smooth as possible. We'll see if it makes a difference.

You guys can always put in double-flush rivets in the few holes that might cause interference. That way you have no worries down the road. Its always easier to take care of things now than when it's all put together. You definitely want to be crawling as little as possible under the panel!

The other option that I figured was available was to use some aluminum stock and create spacers that would elevate the pump beyond the rivets. Thanx for the help guys!
